Subject: [flexcoders] Re: Can not add a Loader object to a container
Thanks for the reply.
I have tried SWFLoader solution, but it seems only loading local
swf file, not an external one referred by an URL.
For the rawChildren solution, I can add loader object indeed, but
how should I handle sizing issue? For example, I want to add this
loader into a titleWindow and make it resizable together with its
container? It seems not a easy thing.
Anyway, my project requires to load external swf into the main
canvas, as an way for user to add their own plug-ins. What is the
best way for this?
Thanks again.

this.rawchildren.addChild(loader)
Containers can only add Flex components to the displaylist. Loader
is a
low level actionscript object.
Using rawchildren, u can add the loader but you have to be
responsible
for the sizing etc.

[flexcoders] Re: Looking for horizontal sliding list/dialog component (like iPhone UI)
Hi! Try using a ViewStack that use WipeRight and WipeLeft effects when hiding and showing a new selectedIndex. This should be a starting point. Thanks, but the problem is, this will not slide the new content in, it will just reveal it. What I need is something like what the accordion does. I took a look at the HAccordion implementation, but it seems to be rather complicated (at least the code there). I'm wondering that there is no component out there, which does this. It is not too exotic. I could have a look at how the IUI iPhone Ajax UI implementation does the sliding, but Flex is to different from JS/HTML to transfer the principles from there...

[flexcoders] Re: Flex is becoming unviable
So how do I make my browser cache the swf? Every time I navigate to my app, the swf loads from the server. As far as comparing html sites with using modules, I think it is very tough to compare such different techologies. But, with the modules I have to wait for another xK bytes module to load which means not a smooth transition. If I was simply doing an html site, we would never go back to the server for such large chunks of data. Using AJAX I would be able to grab much smaller amounts of data (most ajax apps I done would generally only return less that 2k-10k allowing for it to be extremely fast and keeping whatever transition I want. But of course, then all sorts of browser issues with javascript, etc. It there was a way that I could load the modules in the background while the user is doing other things would be great, then it would be there right when I need it. But I think comparing the file sizes of a client side app vs a server side app is apples and oranges. I hope you are right and Adobe is giving this the highest priority as Flex is a very wonderful thing and I'd hate to have it not be as wide spread as it should be because of a serious, but solvable problem.

Modules is essentially the same thing 4) Your app should end up being way more than 500K of small module swfs. A large HTML site can easily end up serving about the same as you view many pages.

To me, that is the same as saying I don't have to worry about poor coding practices that produce inefficient apps because Intel is building faster chips. Adobe needs to put very serious thought into aggressively reducing the size of the SWF files. I'm only into our project about 5%-8% and are already creating 740k swf. I think 500k is too big, by the way. Especially since it needs to download everytime a user comes back. Now if the browser could cache the swf file like it does a graphic, then that would ease my mind a bit. I love flex. It has given me new excitement in my work. But, I agree with the original poster that if Adobe wants flex to become a big player in enterprise apps, they better get this solved quickly. Having the framework cache in the player is a great start, but no where near enough. What is that, about 150k-200k? That puts me still at over 500k and a ton left on the app. My app when done will have 100+ different pages. Modules is another solution, but I see it more as a work around than a fix. For an app the size mine will be, it is probably asking too much to get it down to less than 500k. --- In flexcoders@yahoogroups.com mailto:flexcoders%40yahoogroups.com , Tom Chiverton tom.chiverton@ wrote: On Friday 19 Oct 2007, danielvlopes@ wrote: But i think this is good price to pay.

[flexcoders] Flex sites not running under the URL
HI,
I've posted this message on the Adobe forum, but I thought I'd post it
here too, so sorry for the cross posting, anyway
I have recently been moving some Flex apps onto a new server, now the
problem I'm having is that any Flex app that uses Remoting is only
available via the IP address. When I call the site via the URL I
create in IIS i always get this error message:
mx.rpc::Fault)#0
errorID = 0
faultCode = Server.Processing
faultDetail = (null)
faultString = java.lang.NullPointerException
message = faultCode:Server.Processing
faultString:'java.lang.NullPointerException' faultDetail:'null'
name = Error
rootCause = (null)
Now when I call the same site via the IP address I don't get an error
message and the site works. I've been researching this problem and
asked other people about this and it seems that the problem has to do
with the service-config.xml file, so I've checked my
service-config.xml file and the endpoint entries are fine, e.g:
endpoint
uri=http://{server.name}:{server.port}{context.root}/flex2gateway/cfamfpolling;
class=flex.messaging.endpoints.AMFEndpoint/
Which seems fine, I've also put a crossdomain policy file in the root
of my app and that's not fixing the problem. So I'm stuck for ideas.
Can anyone shed so light and ideas and what to check to solve this
problem?
Thanks
Stephen

[flexcoders] Custom Component not visible on stage
I have created a custom AS component DragObject based on Canvas.
The idea is that ultimately users will be able to put whatever they
want inside this ontainer and it will handle most of the code of drag
and drop for them.
However, when I put another (100 x 100) Canvas inside this component
just to test it out, the width and height of my component are 0, so
it doesn't show up on stage. I used the super() method in my
constructor, so I expected my component to behave like a Canvas in
that it should automatically be sized around its children.
Here is the AS for my class:
package elearning
{
import mx.containers.Canvas;
public class DragObject extends Canvas
{
public function DragObject()
{
super();
}
private var _desc:String = Untitled Draggable
Object;
public function get desc():String{
return _desc;
}
public function set desc(descTxt:String):void{
_desc=descTxt;
}
override public function toString():String{
return(DragObject + _desc);
}
}
}
Thanks!
Re: SPAM-LOW: [flexcoders] Custom Component not visible on stage
I've had similar problems when creating AS3 components. Look into
updateDisplayList. I believe you also have to make sure that your
custom component has a width and height specified.
You can always dig through the canvas code to figure out why that
works, and use that info to figure out why yours doesn't.

The idea is that ultimately users will be able to put whatever they
want inside this ontainer and it will handle most of the code of drag
and drop for them.
However, when I put another (100 x 100) Canvas inside this component
just to test it out, the width and height of my component are 0, so
it doesn't show up on stage. I used the super() method in my
constructor, so I expected my component to behave like a Canvas in
that it should automatically be sized around its children.
Here is the AS for my class:
package elearning
{
import mx.containers.Canvas;
public class DragObject extends Canvas
{
public function DragObject()
{
super();
}
private var _desc:String = Untitled Draggable
Object;
public function get desc():String{
return _desc;
}
public function set desc(descTxt:String):void{
_desc=descTxt;
}
override public function toString():String{
return(DragObject + _desc);
}
}
}
Thanks!

Re: SPAM-LOW: [flexcoders] Custom Component not visible on stage
I'm really talking from a stance of someone who doesn't fully grok how this works yet. With that disclaimer... In my experience, making a component display is not as simple as extending it and calling super() in the constructor. Size it around your children makes sense. Figure out how Canvas does it, and you should be able to figure out why yours isn't working. Or access the children to figure out the size of your custom component. droponrcll wrote: --- In flexcoders@yahoogroups.com mailto:flexcoders%40yahoogroups.com, Jeffry Houser [EMAIL PROTECTED] wrote: I've had similar problems when creating AS3 components.

Subject: [flexcoders] Flex sites not running under the URL
HI,
I've posted this message on the Adobe forum, but I thought I'd post it
here too, so sorry for the cross posting, anyway
I have recently been moving some Flex apps onto a new server, now the
problem I'm having is that any Flex app that uses Remoting is only
available via the IP address. When I call the site via the URL I
create in IIS i always get this error message:
mx.rpc::Fault)#0
errorID = 0
faultCode = Server.Processing
faultDetail = (null)
faultString = java.lang.NullPointerException
message = faultCode:Server.Processing
faultString:'java.lang.NullPointerException' faultDetail:'null'
name = Error
rootCause = (null)
Now when I call the same site via the IP address I don't get an error
message and the site works. I've been researching this problem and
asked other people about this and it seems that the problem has to do
with the service-config.xml file, so I've checked my
service-config.xml file and the endpoint entries are fine, e.g:
endpoint
uri=http://{server.name}:{server.port}{context.root}/flex2gateway/cfamf
polling
class=flex.messaging.endpoints.AMFEndpoint/
Which seems fine, I've also put a crossdomain policy file in the root
of my app and that's not fixing the problem. So I'm stuck for ideas.
Can anyone shed so light and ideas and what to check to solve this
problem?
Thanks
Stephen

Well, in the AJAX apps I've written, even the first downloads were rarely more than 200k, normal 150k. After that, every request was around 2k-10k.

Re: [flexcoders] AdvancedDataGrid and setItemAt()
The selectedIndex is the index of the row in the visual object, which might not be the same as the index of the item in the data provider.

[flexcoders] how to intelligently change datagrid.height dynamically to adjust its rowCount
Hi Guys, How can we can adjust the height of a datagrid dynamically so that it displays a user-specified number of rows?? e.g. If the dataProvider contains 100 elements and I want to adjust the height so that it displays me only 20 rows at a time (with scrollbars), how can i do it ?? Also if the number of rows (dataprovider.source.length) is less than 20 (the user specified number), the height of the datagrid is adjusted so that it takes up space for only those many rows (which is less than 20). Thanks for your help in advance!!!
